摘要：

Three models of a hybrid magnetic suspension system are separately built under the condition of no time-delay, time-delay of the signal of suspension gap and time-delay of arithmetic. To research on the influence of time-delay on the performance of the hybrid magnetic suspension system, relationship between the latent roots of the closed-loop system and time-delay, and the relationship between the stable area of the control parameters and time-delay are analyzed. Results show that both the time-delay of suspension gap and arithmetic bring the latent roots closer to the image-axis and reduce the stable area of the control parameters, which reduce the system's dynamic performance, and even bring the system to be unstable. Conclusions are proved by simulation and analysis.
